Mark and corresponding component title in accompanying drawing: 1, inlet flange; 2a, the first arm; 2 b, the second arm; 2c, the 3rd arm; 2d, the 4th arm; 3, reinforced sheet; 4, gathering tube; 5, mixing tube; 6, reinforcement plate; 7, exhaust flange; 8, transition tube.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is done to detailed description further, but mode of execution of the present utility model is not limited to this.
Embodiment 1:
The constitutionally stable gas exhaust manifold of one as shown in Figure 1, comprise inlet flange 1 and exhaust flange 7, on described inlet flange 1, be vertically fixed with multiple arms, described arm comprises the first arm 2a, the second arm 2b, the 3rd arm 2c and the 4th arm 2d, described arm is all communicated with gathering tube 4, described gathering tube 4 is communicated with mixing tube 5 by transition tube 8, described mixing tube 5 is connected on exhaust flange 7, between described inlet flange 1 and mixing tube 5, be connected with reinforcement plate 6, angle between described gathering tube 4 and inlet flange 1 is greater than 15 degree and is less than 60 degree, described mixing tube 5 parallels with inlet flange 1, on described arm and gathering tube 4, be provided with reinforced sheet 3.In the present embodiment, inlet flange is connected on motor, and engine exhaust is discharged successively after arm, gathering tube 4, transition tube 8, mixing tube 5.Because arm is very short, gas enters gathering tube 4 by arm very soon, gathering tube 4 tentatively mixes gas, enter again transition tube and mixing tube 5, gas is carried out to secondary mixing, gas is fully mixed, utilize twice mixing, increase the path-length that gas is discharged, the impact force while reducing gas discharge.The exhaust of motor enters gathering tube again through arm, be that exhaust meeting produces powerful impact force to gathering tube, the present embodiment is mainly studied the angle between gathering tube inlet flange, scavenging action is studied in the angle of gathering tube, to reduce the impact force of exhaust to gathering tube.Shown by mechanical analysis, when gathering tube parallel with inlet flange, be gathering tube and arm when perpendicular, the impact force of exhaust acts on gathering tube, now completely, the impact force maximum of exhaust to gathering tube, now the structure of gas exhaust manifold is least stable, and it mostly adopts this kind of mode existing gas exhaust manifold, and now, gathering tube has certain rebound effect to exhaust, can make part exhaust get back to arm.When gathering tube and inlet flange not parallel, when gathering tube and arm out of plumb, the impact force of scavenging action on gathering tube is broken off, and reduces perpendicular to the power of gathering tube direction.Experiment and theory all show, when the angle of gathering tube and inlet flange is larger, but can not equal 90 degree, and its exhaust is less to the impact force of gathering tube.Because gas exhaust manifold is connected on automobile, the space size of its vehicle is limited, and in the time that the angle of gathering tube and inlet flange is larger, its space range taking is larger.Angle between gathering tube 4 and inlet flange 1 is 60 while spending, and it can reduce half by impact force, and now, the stability of gas exhaust manifold is fine.Angle between gathering tube 4 and inlet flange 1 is less than 15 while spending, though it can reduce impact force, still, its poor effect.Consider, the angle between gathering tube 4 and inlet flange 1 is greater than 15 degree and is less than 60 degree.Due to the limited space of automobile, by transition tube, mixing tube 5 is paralleled with inlet flange 1, can effectively reduce gas exhaust manifold and take volume, conserve space.In order to make the degree of mixing of gas high, mixing tube 5 has certain length, and reinforcement plate 6 is fixed mixing tube, further strengthens the stability of gas exhaust manifold.Reinforced sheet 3 is arranged on arm and gathering tube 4, strengthens the linkage structure of arm and gathering tube, strengthens the stability of gas exhaust manifold.
Embodiment 2:
The constitutionally stable gas exhaust manifold of one as shown in Figure 1, the present embodiment is preferred one group of data on embodiment 1 basis, and the angle between gathering tube 4 and inlet flange 1 is 20 degree.
Embodiment 3:
The constitutionally stable gas exhaust manifold of one as shown in Figure 1, the present embodiment is preferred one group of data on embodiment 1 basis, and the angle between described gathering tube 4 and inlet flange 1 is 30 degree.
